The problem is how to protect your e-mail messages from being compromised through the GNU Privacy Guardian. If GPG (GPG is a set of toolset for secure communication and data storage that can be encrypted and digitally signed) is not properly used, it is not possible to obtain security recognition from the information. It is entirely possible to insert additional information before and after the data is encrypted, and it is safe to mistake the user for the data. Using cryptographic techniques to authenticate or encrypt e-mail messages is quite dangerous. ...

GPG, the GNU Privacy Guard, is a non-commercial version of cryptographic tool PGP (pretty), which is used to encrypt and authenticate emails, files, and other data to ensure the reliability and authenticity of communication data.
